6. Apply Flashing Tape
Unit must be properly flashed and sealed for protection against water and air infiltration. Use non-reflective
flashings. Highly reflective flashing tapes can raise the surface temperature of the vinyl to the point where
vinyl deformation and product damage may occur.
• This instruction step depicts one of many options for proper flashing.
• Moisture infiltration problems in any type of building can be reduced by properly flashing and/or sealing around all
building openings, including windows and doors. Proper flashing under and around window and door openings can
reduce moisture problems, but the performance of any building system depends upon the design and construction of
the building system in its entirety, which should address local environment, climate, building codes and product and
material limitations. The design and installation of flashing and sealing systems are the responsibility of the architect,
contractor, installer, and/or the manufacturer of the building exterior specified for the project.
• Apply Drip Cap (full width).
• Apply flashing tape over Installation Flange at sill.
• Apply flashing tape over Installation Flange at sides,
overlapping flashing tape at sill.
• Apply flashing tape over Drip Cap (full width) and
Installation Flange at head, overlapping flashing tape
at sides.
7. Insulate and Seal Unit
When insulating between unit frame and rough
opening or between units when joining, DO NOT
overpack batt insulation or overfill with foam.
Bowed jambs will result affecting product
performance and/or proper operation of unit.
A minimum space of 1/4" is required around
exterior perimeter of unit between frame and
siding. Masonry/Brick Veneer installations require
a minimum 1/2" space along sill and 1/4" space
around the remaining perimeter.
• Insulate between frame, extension jambs, and rough opening
on all sides. DO NOT overpack or overfill with insulation;
bowed jambs may result.
• Apply backer rod and sealant around exterior perimeter of
window after siding (or other exterior finish) is applied.
